The singer, who launched her new collection at the Oxford Street store, said her clothes were aimed at a variety of women as well as pieces she would wear herself. Pop superstar Rihanna has admitted she was a "little bit selfish" when she was designing her range of clothing for River Island - a career move she referred to as "the dream". Dressed in a tight, floor-length black gown and with her hair hanging in loose curls over one shoulder, the Barbados native stopped with waiting journalists to chat about her latest venture. The 25-year-old star said she was in disbelief as she reflected on the creative process, all the while admiring the cropped tops, slashed-to-the-thigh dresses and bright neon colours. "From where we started, from jotting these down on napkins and pieces of paper in the hotel room in the middle of the night. It's scary. "I mean, I'm so happy. I can't even believe it," she said. Rihanna said her clothes were aimed at a variety of women, but said they are all pieces she would wear herself. She said: "I would wear everything here. I was being a little bit selfish. "I designed everything that I would want to wear, and for the women that I'm with. "I'm with a large group of women who have different sizes, different tastes, different body types. "I wanted to design something that everybody could wear because I wanted all my friends to have something too, but I'd still wear everything."
